Bear in mind that Correlation is a function within an AddOn package:
Statistics`MultiDescriptiveStatisitcs`. If you don't load this package prior
to calling Correlation, Mathematica won't recognize the name. If you have
inadvertently tried to use the function before loading the package you must
remove it first. Try this (and be careful with the " ` " sign: it is the
French accute, and not a quotation mark " ' "):
In[1]:=
Remove[Correlation]
In[2]:=
<< "Statistics`MultiDescriptiveStatistics`"
In[3]:=
Correlation[xlist, ylist]
Out[7]=
